Given numbers are 838,747,913,856
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 838,747,913,856 is 2947142088.
Find LCM of 838,747,913,856 with Prime Factorization
2 | 838, 747, 913, 856 |
83 | 419, 747, 913, 428 |
419, 9, 11, 428 |
Multiply the prime numbers at the bottom and the left side.
2 x 83 x 419 x 9 x 11 x 428 = 2947142088
Therefore, the lowest common multiple of 838,747,913,856 is 2947142088.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
838 x 747 x 913 x 856 = 489225586608
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
838 : 1, 2, 419, 838
747 : 1, 3, 9, 83, 249, 747
913 : 1, 11, 83, 913
856 : 1, 2, 4, 8, 107, 214, 428, 856
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 838,747,913,856, is 1.
Now, the common factors can be found like this.
838:2x 419
747:3x 3x 83
913:11x 83
856:2x 2x 2x 107
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 83 = 166
Therefore, the value for common factors is 166.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 489225586608/(1x166)
LCM = 489225586608/166
LCM = 2947142088
Thus, we can understand that the LCM of 838,747,913,856 is 2947142088.
